BUTTON OR STUD.

SPECIFICATION formingpart of Letters Patent No. 667,631, dated February5, 1901.

Application filed September 10, 1898. Serial No. 690,673. (No model.)

To all whom, it may concern.-

Be it known that I, HALSEY M. LARTER, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Buttons or Studs; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention relates to that class of buttons or studs represented bythe one shown in my prior patent dated December 13, 1898, No. 616,057,the objects of the said invention being to reduce the cost ofconstruction, to facilitate manufacture, to secure a more durable,simple, and effective structure, to enable the oross-head or footadapted to lie inside the shirt-front to be more centrally disposed inits relation to the post of the button, and thus avoid the objectionsdue to a short projection of the cross-head at one side of the postheretofore made necessary because of the use of a short spring requiredby the common construction, and to secure other advantages and results,some of which may be referred to hereinafter in connection with thedescription of the working parts.

The invention consists in the improved button or stud, in thespring-back therefor, and in the arrangements and combinations of parts,all substantially as will be hereinafter set forth and finally embracedin the clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several views,Figure 1 is a side elevation of my improved button. Fig. 2 is alongitudinal section of the same on an enlarged scale. Fig. 3 is atransverse section at line 41;, Fig. 2; and Fig. 4 is a plan of acertain plunger or piston.

In said drawings, a indicates the head of the button, adapted to lieoutside of the shirtfront and be ornamented, set with jewels, or given aplain finish in any ordinary manner common in jewelry.-

The shankb of the button consists of a piece of metal tubing, extendingperpendicularly backward from the head a for a suitable distance to forma post I), and being bent at right angles to itself to form one arm orbarrel b of the cross-head of the button, which cross-head lies againstthe inner surface of the garmentand holds the stud in place. The head ofthe button is soldered or otherwise fastened to the end of the post 12,and the arm or barrel 1) lies parallel to the shirt-front, as will be understood, the bend in the shank being curved or rounded to facilitateits passage through the buttonhole or eyelet. In the said arm orbarrel 1) of the tubular shank is arranged a plunger d, which workstelescopically within said barrel. The said plunger is considerablylonger than the barrel formed by the arm I) and projects therefrom atits opposite ends, the amount of normal projection from the bend in theshank being sufficient to form the other arm of the cross-head, of whichthe barrel is one arm. The said barrel is open at its forward or freeextremity and is perforated at the rounded angle, as at c, in line withthe bore of the barrel to permit of the outpassage of said piston orplunger d, as will be understood upon examination of Fig. 2.

In my prior application ldescribed a shank which was of a solid wirebored out at its opw posite ends after being bent, as herein shown, oneboring reducing the weight of the post or shorter arm of the shank andthe other boring 8 5 forming the barrel. In the present case I securesubstantially the same strength by using the tubular shank and a fillerc, of solid Wire, which fits closely within the chamber or bore of theshank and is of a length sufficient to lie in and fill the curved orrounded bend. I thus secure by means of the filler increased strength atthe rounding and avoid the skill, care, and expense required in boring,as heretofore. Inasmuch as the shank is bent after the introduction ofsaid filler c, the latter is firmly held in place in the rounded bend,and after the bending is accomplished the end of the filler may be boredthrough in perforating the side of the shank near the rounded 10o bendto allow the outpassage of the plunger at c, as has been described' Thesaid plunger d is tubular and has a spiral spring e, arranged therein,which normally draws the forward or handled end of the plunger back intothe barrel.

The plunger d is tubular to receive what may be termed the rearward partof the spring e, which spring thus lies normally partly in the arm orbarrel b and projects out therefrom into the projecting part of theplunger forming the movable member of the cross-head. Said spring thusserves to return the handled or knobbed end of the plunger into thebarrel, and inasmuch as the spring, lying as it does in both the barreland normally projecting part of the plunger, may be made longer than byprior constructions, the distance of movement of the plunger and thenormal projections of the plunger can be correspondingly increased, sothat the projection of the barrel at one side of the post and theprojection of the plunger at the opposite side will be about of equallength. By this construction the cross-head cannot be drawn through theslotted buttonhole of the shirt because of the length of the movable armof the cross-head, and the improved button can be used equally as wellwith oblong buttonholes as with round eyelets. The side of the plungertoward the head a is slotted longitudinally, as at f, and at theprojecting end of the barrel I form an integral lip c, which is bentinward or toward the longitudinal axis of the barrel, as shown in Figs.2 and 3. This lip serves as a stop or, more particularly, as an endbearing for the spiral spring 6 and is of a width suited to enter thelongitudinal slot f of the plunger or piston, the said slot extendingout to the forward extremity of the plunger, as shown in Fig. 4, topermit the insertion of said lip when assembling the parts.

In the construction disclosed in the case above referred to I have shownand described a block which was inserted in the end of the barrel andheld therein by a pin or screw. By my preferred construction I avoid thetrouble and expense of fitting the parts and the cost of metal employedin the same and also the danger or liability of the dropping out of thepin from its bearings, resulting in disassociation of parts.

The forward end of the tubular plunger is provided with a conicalfinger-cap g, the edge of said cap being turned over the flaringextremity of the barrel, as shown in Fig. 2. The opposite end of thetubular plunger is closed to provide an interior bearing for the springe, either by filling said tube with solder, inserting a block of metaltherein and holding it in place by any suitable means, or by swaging thetube, so as to force the metal thereof toward the axial center, and thusform the desired hearing. The end thus closed is at its outside beveledor rounded, as at h, (shown in Figs. 1 and 3,) and conforms in outlineto the convex surfaces at the bend in the shank. At the beveled orrounded extremity the plunger is provided at the end of the bevelfarthest from the shank with a stop projection (1, adapted to enter asmall recess '6 in the shank, the said projection engaging the innerwall of the recess, and thus limiting positively the movement of theplunger against the pressure of the spring and pre venting unduepressure being exerted upon the lip c and guarding said lip c frominjury.

Having thus described the invention, what I claim as new is- 1. Theherein-described stud or button comprising a recessed shank formed of apiece of metal tubing bent at right angles and having the bend roundedto facilitate passage through a buttonhole, a head fastened to one endof said shank, a solid filler arranged inside at the bend and a tubularplunger in the other end, the shank and filler being perforated at thebend to provide an outpassage for said plunger, an integral lip bentradially inward at the free end of the arm in which the plunger lies andthe plunger being longitudinally slotted to receive said lip, a spiralspring 1ying in said plunger and bearing at one end against said lip andat the other end against the closed end of the plunger, a conical cap atthe forward end of the plunger and a stop projection d, at the rear endadapted to enter a recess '5, in the shank and engage the filler tolimit the forward movement of the plunger, substantially as set forth.

2. In a stud or button,the combination with a head a, and shank I),having a tubular arm I), parallel to the said head and open at bothends, of an integral lip c, at one extremity of said arm and bent inwardto lie across the bore of said arm, a hollow plunger sliding in the saidarm and projecting therefrom at both ends and being slotted to receivesaid lip c", a spiral spring arranged in said plunger and hearing at oneend against said lip and at the other against the closed end of theplunger, an outwardly-projecting stop at said closed end of the plungerand means on the shank for engaging said stop and limiting the forwardmovement of the plunger, substantially as set forth.

3. In a stud or button, the combination with a head a, of a hollow shankb, bent at right angles to form an arm or barrel 1), and post b, saidshank being round at the bend, a filler 0, arranged in the shank at saidbend, and a longitudinally-slotted hollow plunger d, sliding in the armor barrel, which arm or barrel is parallel to the plane of the head,said shank and filler being perforated at the bend to allow a slidingmovement of the plunger and said arm or barrel having, at the endopposite said bend, an integral lip projecting inward through said slotin the plunger, and a spring arranged within the plunger and the arm orbarrel 1), and at one end bearing against the end wall within theinterior of the plunger and at the other end bearing against the saidlip, a finger-piece at the forward end of the plunger for drawing itforward, and a stop d, at the rear end to engage the shank and limit theforward movement, substan tially as set forth.

4. The improved stud or button comprising a tubular shank bent at rightangles, provided With a head at one end perforated at the bend, andforminga tubular arm or barrel 1), at the other end, substantiallyparallel with the head, the said tubular arm or barrel Z), being open atthe end opposite the perforation at the bend of the shank, an insertedfilling-piece independent of the tubular shank and bent in conformity tothe bend of said shank and fitting the interior thereof, a plunger d,lying in said tubular arm 01' barrel and having its forward end providedWith a knob or finger-piece and its opposite end beveled to fii the bendof the shank and means for retaining the plunger Within the tubular armor barrel, substantially as set forth.

5. In a stud or button the combination with the tubular shank, b, bentat right angles to itself with a rounded bend and having a filler c,inserted in said bend, said shank being perforated at the bend in linewith the bore of that portion of the shank lying inside the garment, ofa plunger sliding in the barrel thus formed and having its rear endbeveled and rounded to conform to the rounded outer surface at the bendin the shank and having a stop adapted to enter a recess in said shankwhen the plunger is drawn forward and limit the movement so that the endof the plunger shall lie flush with the surface of the shank and closethe perforation therein, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of July, 1898.
